Based on simulation experiments with and without sulfate,the authors comparatively analyze the gas components obtained from experiment,and then investigate the rule of alteration in TSR-altered gases.The result shows: TSR advanced the total gas production rate of samples and the main portions are non-hydrocarbon gases,which refers to that high-pressure gas reservoir can be generated easily because of TSR alteration in the consistent condition of porosity and temperature; production rate of methane is low,and the influence of TSR on production rate of methane is relatively great.Because organic matter may be under joint action of pyrolysis and TSR,it is not sure whether TSR-altered methane can cause of decease of methane production rate or not; the impaction of TSR on production rate of ethane may be related to organic matter type.Ethane production rate of typeⅢorganic matter increases,whereas that of typeⅠ and typeⅡ organic matter deceases due to TSR.The possible cause is that typeⅠand typeⅡ are more prone to TSR than type Ⅲ.In the consequence,the formers′ capability to form ethane is relatively weaker; the content of hydrogen sulfide is less than that of carbon dioxide in experiment,but it is generally converse in geological field.The formation of bicarbonate due to the combination of carbon dioxide and calcium ions may be the main reason for the reduction of carbon dioxide.Fraction process of carbon dioxide probably advances the property of reservoir a lot.
